Teeth whitening or veneers: is a lighter shade enough, or do you need a new surface?
Most people who ask about veneers begin with a simpler wish: brighter teeth. Whitening answers that wish directly. It lightens your own enamel over a few weeks at home, costs a few hundred pounds and changes nothing about the structure of the teeth. Veneers go much further, replacing the whole visible face of each tooth with ceramic or resin, and are the right tool when colour is only part of the problem. This page starts from the whitening end of the spectrum and asks when it is sensible to stop there, and when it is worth going on to veneers.
Decision guide
Which is right for you?
Choose Teeth whitening if…
- Your teeth are a uniform yellow or have dulled with age, coffee or tea.
- The teeth are well shaped and you have no chips, gaps or crowding to correct.
- You would rather spend hundreds than thousands and see how far a lighter shade goes.
- You want to keep every option open with no enamel removed.
Choose Veneers if…
- Whitening has plateaued and the colour is still uneven, banded or grey.
- You also want to lengthen worn teeth, close spaces or square up an irregular edge.
- You have front teeth with old fillings or bonding that would not lighten and would show against whitened enamel.
- You are looking for a result that holds its colour for a decade or more.

| Time to result | Two to four weeks | One visit (composite) or two to three weeks (porcelain) |
| Tooth preparation | None | Little for composite; a thin layer of enamel for porcelain |
| Fee at Wimpole Street | £399 | From £595 per tooth (composite) or £1,095 (porcelain) |
| How long it lasts | Around 6 to 12 months before a top-up | 5 to 10 years (composite) or 10 to 20 years (porcelain) |

What the treatment involves
Teeth whitening
After a check that the teeth and gums are healthy, and a hygiene visit if there is surface staining, a scan is taken and thin custom trays are made. You receive the trays and syringes of Boutique whitening gel with clear instructions on how much to load and how long to wear them, usually overnight or for a set period each day. The active ingredient diffuses into the enamel and breaks down the pigments held within it, so the teeth lighten progressively over two to four weeks. Any sensitivity is managed by shortening wear time or pausing for a night. A review compares the result with the starting shade, and the trays are kept for top-ups as the colour gradually returns over the following year.
Veneers
Veneers begin with a design conversation, photographs and a scan, often followed by a mock-up you can see in the mouth before anything is done. For composite veneers the dentist then sculpts resin directly onto each lightly prepared tooth in a single appointment, layering shades to mimic enamel and dentine and polishing the result. For porcelain, a fine layer of enamel is removed under local anaesthetic, a scan goes to the laboratory and temporary veneers are worn for a week or two while the ceramic shells are made. At the fitting visit each veneer is tried in, the cement shade chosen and the veneer bonded and cured. Whitening the remaining teeth, if planned, is done before the shade for the veneers is chosen.
Fees
Cost and longevity at Wimpole Street
Boutique home whitening at Wimpole Street will be £399. Veneers will start from £595 per tooth in composite and £1,095 per tooth in porcelain, so six porcelain veneers represent a commitment in the region of £6,500 or more, while whitening the same six teeth costs a fraction of that.
Whitening needs refreshing every 6 to 12 months but the trays are reused and the top-up gel is inexpensive, so its running cost stays low. Veneers last far longer, 5 to 10 years for composite and 10 to 20 years for porcelain, but eventually need replacing at a similar fee. Because whitening removes no enamel, trying it first costs you nothing in options: if the result satisfies you, the matter ends there; if it does not, the veneers are simply matched to the lighter shade.
All prices are indicative and are confirmed in a written treatment plan at your consultation. Fees are the same at every Medical & Dental clinic.

FAQ
Common questions
Yellow and brown staining from age, diet and smoking responds well. Grey tones, horizontal bands from childhood antibiotics and white flecks from fluorosis respond poorly or unevenly. A shade assessment and a look at the pattern of discolouration at the consultation give a fair indication before you commit.
No. Veneers are rarely placed on every tooth, so the whitened teeth beside and behind them set the shade for the veneers and continue to benefit. Most veneer plans include whitening beforehand for exactly that reason.
Usually not quite. Whitening brightens your own enamel and is limited by the dentine beneath; veneers can be made to any shade you choose. That is an advantage or a drawback depending on taste, since very uniform white teeth can look less natural.
For the first day or two after each session the enamel is more porous, so avoiding strongly coloured drinks helps. After that, normal habits resume; they simply determine how soon you reach for the top-up gel.
Yes, and this is a common compromise. The rest of the smile is whitened first, and a veneer or two is then made to match on the teeth that are chipped, misshapen or resistant to whitening.
Yes. South Kensington and St Paul’s offer whitening consultations and veneer planning now at identical fees, and any whitening started there can be reviewed at Wimpole Street once it opens.
